  Although not shown here, the joint portion 21 may be formed of plastic and fitted to the bottom surface 12 of the tableware 2 or joined in a screw shape. At this time, a metal thin film may be attached to the joining portion 21 plastic-molded into a plate shape to form the metal plate 22, or metal may be deposited to form the metal plate 22.

  As a use here, when using it for the use which warms the hot water of a cup, it is the temperature range of 100 degrees C or less, and it can cover with the heat resistance of plastics (for example, the heat deformation temperature of nylon 180 to 240 degreeC).

  With this configuration, the eating and drinking tableware 2 can be directly heated by the electromagnetic cooking device 10 and used as it is as a tableware. Even if the thermal expansion coefficients of the metal plate 22 and the main body 11 are different, the joining portion 21 absorbs the thermal expansion of the metal plate 22 and the main body 11, so that the metal plate 22 and the main body 11 are peeled off and damaged. Can be prevented.

  In addition, the junction part 21 is not restricted to this shape and structure, What is necessary is just a shape which fixes the main body 11 and the metal plate 22 so that attachment or detachment is possible. Further, the joining portion 21 may be fixed by adhesion or the like without being attached to or detached from the main body 11. Similarly, the metal plate 22 and the joint portion 21 may be fixed by adhesion or the like. Furthermore, the metal plate 22 is not limited to stainless steel, and any material that is heated by the electromagnetic cooker 10 may be used.
